Dedicated to Saints John and Paul, this cavernous church is one of the largest in Venice. It's often called "the Pantheon of Venice" because of the doges' tombs within. An important stop on the art-history circuit, it houses paintings, including Giovanni Bellini's The Polittico di San Vincenzo Ferreri and three by Paolo Veronese. The Monument to Doge Pasquale Mocenigo is a masterpiece by sculptor Pietro Lombardo. In the square out front stands Andrea Verrocchio's monument to Bartolomeo Colleoni. This famous mercenary requested a statue in San Marco as his battle payment. The clever doge agreed, but instead of putting the figure on the piazza, he had it placed in front of the Scuola di San Marco (the San Marco School). Open daily 7:30 am-6:30 pm. Ticket office closes one hour before closing. 2.50 euros. Campo dei Santi Giovanni e Paolo, Castello, Venice. Phone 041-523-5913.
